Wayne Cosby has lots of good information on the men themselves, at least on Company F. I would contact him and let him know what you're looking for.

Besides the regimental flag the flag of Company F survives. There was also a "free man of color" who enlisted when the company was formed. I had one 2nd great-grandfather and two 3rd great-uncles who served in this company. One, Benjamin Henry surrendered at Appomattox under Lee. I look forward myself to seeing more on this regiment.
